GreenSlope is a roof leveling compound that helps eliminate ponding water on flat rooftops by filling in low areas, returning the roof to its original slope to achieve positive water flow to desired drainage areas. Following advanced in-house innovation and successful market testing, GreenSlope has been re-engineered for 2018 and now ships with a new and improved formula.

GreenSlope’s new formula features an improved adhesive, dramatically shortening the curation period from 24 hours to 2 hours, which allows for same-day topcoating. GreenSlope has also upgraded to finer-grade EPDM granules, which are less porous, easier to work with, and offer superior UV resistance and longevity. GreenSlope’s robust adhesive forms an exceptional bond with a wide variety of roof systems including single-ply, modified bitumen/BUR, metal and foam roof systems. The cured material is similar to a professional running track or premium playground surface, able to withstand extreme climates and as well as foot traffic.

At 20 percent the weight of concrete alternatives and half the weight of ponding water, GreenSlope reduces stress on the roof system by facilitating proper water drainage to extend the lifespan of the roof at a fraction of the time and cost it takes to install a new drain or tapered insulation. GreenSlope’s UV-stable compound can endure frequent freeze/thaw cycles and resists wear and tear while remaining flexible to absorb surface stresses. Highly malleable, GreenSlope can be used in a wide variety of practical scenarios including around low drains and scuppers, as walk pads and pitch-pan filler, for protection around curbs, HVAC units and more.

The product can be easily applied over low areas using a trowel and straightedge to smooth and level. For best results, additional topcoat application is recommended to achieve reliable waterproofing and match the aesthetics of the existing roof. GreenSlope is compatible with most topcoats including white acrylic, aluminum mastic, modified mastic, elastomerics, emulsions, and membranes.

The problem of ponding water offers service divisions an opportunity to open new doors with prospective clients. Ponding water can be found on eight out of 10 flat roofs and is one of the most commonly reported concerns of contractors and building owners as it can cause leaks, structural damage, membrane damage, algae and mold growth, slip hazards, insect problems, voided warranties, and premature failure of roof systems. Conventional options to deal with ponding include installing a new inner drain or adding tapered insulation, but these options are often expensive for building owners and not always necessary. GreenSlope’s preventative approach helps building owners maintain their roof asset while maximizing rooftop ROI. Additionally, going green offers potential LEED credits.

GreenSlope is manufactured and distributed by United Asphalt.

CertainTeed offers RoofRunner, a high-performance synthetic roofing underlayment, bringing additional versatility to CertainTeed’s roofing product line. At just 23 pounds per 250-foot roll, RoofRunner is easy to handle, according to the company, with a high-traction surface designed for wet or dry walkability.

According to the manufacturer, RoofRunner is very durable and water resistant. The product features 90-day UV exposure and resists tearing caused by stretching, high winds and foot traffic. The underlayment is designed to firmly grip to the roof deck, providing a stable surface for builders and reducing pulling against mechanical fasteners. Its light gray surface offers a cool working environment, so those working on roofs all day have fewer worries about overheating.

RoofRunner exceeds the performance requirements of ASTM D226 and D4869, notes the company. It conforms to UL 790/ASTM E108 for Class A fire resistance, is Florida Product Control Approved, and also conforms to the ICC-ES AC188 standard. RoofRunner qualifies as a component in CertainTeed’s Integrity Roof System.

Kemper System America Inc. now offers two cost-effective ‘cool roof’ solutions for prolonging the life of metal, BUR, modified bitumen and aged single-ply roof systems.

Roof Guardian RG-170 is an elastomer-based coating system ideal for extending the life of many types of roofing assemblies. Formulated using a 100 percent acrylic polymer base for enhanced adhesion and durability, the coating features a high Solar Reflectance Index (SRI) rating of 109 and is Class A fire rated. Roof Guardian RG-180 is a fiber-reinforced elastomeric coating with an acrylic polymer base, ideal for metal, concrete, single ply, modified bitumen, and granular cap sheets. It offers an SRI rating of 108.

“Kemper System has been at the vanguard of liquid-applied roof waterproofing solutions for decades. These two new white Roof Guardian coating systems offer a quick and cost-effective approach for transforming many kinds of existing low-slope roofs into a cool roof that can help building owners cut cooling costs,” says Jim Arnold, Director of Product Development for Kemper System.

Part of the company’s Roof Guardian Technologies line, the roof coatings can be quickly applied with a commercial-grade sprayer or roller. The highly reflective bright white finish lowers the surface temperature of the substrate to reduce thermal transfer into the structure. This high solar reflectance helps lower indoor temperatures to reduce building cooling requirements.

“For more than 60 years, Kemper System has been a global industry leader in cold liquid- applied, reinforced roofing and waterproofing, having invented the technology and holding the first patents,” says Arnold. “Today the company offers a full range of building envelope solutions to protect against weather, preserve the integrity of surfaces, and enhance the comfort and value of buildings.”

Because Rich-E-Board roofing insulation is light and easy to install, it lowers the cost of delivery and handling and can reduce labor costs by more than half.

It’s exceptionally thin and easy to install. It delivers an R-value of 50 to commercial, industrial and government buildings. Now, Rich-E-Board, the innovative new roofing insulation, is enjoying a groundswell of interest from building
owners, contractors and architects seeking to drive down construction costs and boost energy efficiency.

Rich-E-Board recently received a patent for its proprietary Vacuum Insulated Panel—two polymeric foam cover boards that sandwich the panel—and the adhesive ribbons that bind the boards and panel together. This ultra-thin insulation offers a certified alternative to a huge commercial roofing market—billions of square feet in construction every year—challenged with
meeting stringent standards for energy efficiency.

While conventional insulation requires a thickness of 15 inches to reach an R-value of 50, Rich-E-Board achieves the same result at just 1.5 inches thick. Rich-E-Board can be installed on most roof deck types, including ballasted roof systems, and can support all conventional low-slope roof systems.

Rich-E-Board’s design delivers significant advantages:

Lower energy bills: Achieving an R-value of 50 can cut a building’s heating and cooling costs by 8 to 10 percent, according to the GSA.

Simpler retrofits: Rich-E-Board enables retrofitted structures to achieve required R-values in less time, with fewer materials, and without costly and destructive building modifications.

Reduced construction costs: Because Rich-E-Board is light and easy to install, it lowers the cost of delivery and handling and can reduce labor costs by more than half.

Rich-E-Board is also fireproof and water and mold resistant, notes Joanne Collins, president and CEO of R-50 Systems, maker of Rich-EBoard. “Our team focused on creating a game-changing alternative,” Collins says. “Rich-E-Board fills a significant
void in the marketplace by providing an insulation system capable of meeting today’s tougher energy standards.”

Success in the Field

Rich-E-Board has made a successful transition from the drawing board to the marketplace. Owners and architects have taken advantage of the insulation’s slim profile and high R-value on several building projects.

At a government building in Chicago, for example, owners chose to install 3,600 square-feet of Rich-E-Board as part of a roof retrofit aimed at lowering lifetime energy costs. Rich-E-Board’s slim profile also cut construction costs by more than $20,000 by streamlining design and installation.

At the Cohen Courthouse in Camden, N.J., Rich-E-Board was selected for the roof retrofit, eliminating the need for expensive building modifications that would have been required for conventional insulation. The decision lowered the project cost by $200,000.

Earlier this year, Rich-E-Board was awarded a patent for its design. More recently, the insulation earned its first LEED 4 designation.

“We’re seeing a huge increase in Rich-E-Board as the roofing market learns more about the benefits it brings to the commercial roofing,” Collins says. “This product fills a significant void by providing an insulation system capable
of meeting today’s tougher energy standards.”

Collins notes that, in addition to the $5 billion annual market for commercial roofing, Rich-E-Board can be used in walls and other building applications. Rich-E-Board is 99 percent recyclable and made entirely in the U.S.

The butyl sealant can be used in a variety of metal roof applications where a low modulus sealant is desired.

R.M. Lucas Co. has added a single-component, non-skinning butyl rubber sealant to its product line. Lucas #8660 provides adhesion and a permanent seal between concealed end laps, metal roof panels, standing-seam roof panels, ridge caps, wall panels and other applications where a non-hardening weather seal is desired. This product is also ideal for use with OEM and shop-assembled metal details.

“Lucas #8660 won’t stain substrates and exhibits primerless adhesion to most roofing and building materials, including Kynar,” says Jason Morris, technical sales representative for Lucas. “The product is easy to gun and tool, even in cold weather, and is also self-healing.”

The butyl sealant can be used in a variety of metal roof applications where a low modulus sealant is desired, including metal roof panels, ribs, standing seams, and ridge cap flashing, as well as metal wall panels. Lucas #8660 is also recommended for OEM trailer and RV application, installation of walk-in coolers and freezers, and as a vapor barrier sealant. In addition, Lucas #8660 can be used as a sound-deadening sealant in installation of acoustical ceilings as well as both gypsum and metal wall panels. It is not designed for use as a single-ply roofing adhesive or lap adhesive.

When applying the sealant, the surface to be sealed must be dry and free of dirt or loose corrosion particles. A primer is not needed. Simply apply the sealant to the area as desired. Tooling is not normally necessary. The product can be cleaned with Lucas #125 Safe Solve. It also has a long shelf life, remaining active two years from the date of manufacture.

“We feel that this will be an excellent addition to our product line whether you are restoring, renovating or maintaining building structures,” states Morris.

Designed with the installer in mind, Surround VR Underlayment reduces the amount and weight of material needed for roofing jobs. In fact, one roll of Surround VR covers the same area as five rolls of 30# felt, yet weighs seven times less and is 10 times stronger.

The waterproof product was developed to work in nearly any roofing application, including with shingles, shakes, tile, slate or metal roofs. “With our new Surround VR Underlayment, installers will make fewer and easier trips up and down the ladder while experiencing faster installs, all while providing a more durable roofing system to their customers,” says Jorge Martinez, senior director of Product Marketing, TYPAR brand.

Made from a waterproof, synthetic polymer material, Surround VRUnderlayment is engineered to repel moisture and will not warp or buckle when wet, thus helping to maximize the life of the roof system. Surround VR is also slip-resistant on dry surfaces and provides better traction when wet.

The underlayment maintains its integrity year-round, performing well in temperatures ranging from -40 to 240 F. In cold temperatures, the material will not crack or wrinkle, which helps ensure smooth installs. In warm temperatures, its heat-reflecting, gray-colored surface reduces heat buildup on the roof. Surround VR also can withstand up to six months’ exposure to UV light and high winds and storms, even those experienced by coastal regions.

Surround VR Underlayment is backed by a 15-year product replacement warranty and is suited for residential and commercial applications.

Malarkey Roofing Products released the Legacy XL and Windsor XL high-profile shingles in June. The new heavyweight shingles offer a more pronounced design on the roof while maintaining the fortified durability of their original shingle lines.
